Battery case surface protection treatment process

Abstract

The invention relates to the field of battery processing, and particularly relates to a battery case surface protection treatment process. The battery case surface protection treatment process uses abattery case treatment device, the battery case treatment device comprises a base and fixing frames, transmission gears are symmetrically arranged in the base, a conveying belt is arranged between thetransmission gears, a conveying groove with an annular structure is formed in the base, the conveying groove and the conveying belt are symmetrically arranged and communicate, a plurality of socketsare symmetrically and fixedly installed on the side, away from the transmission gears, of the conveying belt, through grooves are formed in the sockets, the plurality of fixing frames are inserted into the through grooves, a rotating gear is fixedly installed at one end of each fixing frame, and racks are fixedly installed in the conveying groove. the rotating gears and the racks are symmetricallyarranged, the ends, away from the rotating gears, of the fixing frames extend out of the conveying groove and are fixedly provided with a plurality of supporting plates with circular structures. Thebattery case surface protection treatment process can coat multiple battery cases at the same time, and is suitable for popularization.

Description

technical field [0001] The invention relates to the field of battery processing, in particular to a battery casing surface protection treatment process. Background technique [0002] A battery is a device used to store electrical energy. It is very common in modern daily life. Most of the common batteries are cylindrical, and they are wound into a cylindrical shape through a metal casing to tightly wrap the chemical materials in the battery to avoid battery damage. Leakage of chemical raw materials inside. [0003] Conventional battery casings are basically made of steel. After the battery casing is cast, in order to avoid corrosion of the battery casing, it is necessary to apply a protective coating on the surface of the battery casing to improve the protective effect of the battery casing. Most of the current battery casings The protective coating is processed by roller application. This method can make the protective coating on the surface of the battery case evenly dist...

[0003] Conventional battery casings are basically made of steel. After the battery casing is cast, in order to avoid corrosion of the battery casing, it is necessary to apply a protective coating on the surface of the battery casing to improve the protective effect of the battery casing. Most of the current battery casings The protective coating is processed by roller application. This method can make the protective coating on the surface of the battery case evenly distributed without affecting the inner wall of the battery case. However, it is easy to squeeze the battery case when the roller is applied. , causing deformation of the battery case, which affects the coating effect and the use of the battery case, and the conventional roller coating can only process a single battery case and cannot be adapted to batch processing
